HSn70-1AB Brass Tube For Corrosive Liquids In High Strength And
Corrosion Resistant Condenser
1. Description
HSn70-1AB alloy condenser tube is a new type of
alloy pipe. It is based on copper, tin and zinc alloy, with the
synergistic effect of arsenic, boron, nickel and manganese
elements. It has high corrosion resistance and erosion corrosion
resistance.
It's belonged to condensing tube series, the
chemical composition of the HSn70-1AB alloy tube is copper and
arsenic, and the residual is zinc. Its superior performance is to
prevent stress corrosion cracking, pitting, and erosion. The
product is generally used in rivers, lakes and springs, as well as
inland power plants with fresh and clean water. In addition, it can
also be used in liquid and juice processing equipment, and also
widely used in sugar and food industry.
Our company's brass tube grades mainly
include HAi77-2,HSn70-1, HSn70-1B, HSn70-1AB, H68A copper
tube, fin tube and U-tube. The products are produced in strict
accordance with the standard, and the finished products can be
tested by the third party according to the customer's requirements.
These copper tubes are mainly used in power plants, desalination,
petrochemical, mechanical ships and automotive heat exchangers. We
have rich production experience, professional technology, excellent
equipment, superior quality, reasonable price, high-quality
service, so that our products sell well all over the world, well
received by customers.
